PDFAbstract
Objective To investigate the value of PI-RADS V2 combined with MRI in the diagnosis of peripheral prostate cancer (PCa). Methods A total of Twenty-three patients undergoing MRI examination were analyzed for T2WI, DWI, and DCE images. The subarea of the prostate peripheral zone was scored according to the 6-partition method. T-tests were performed on MRI of T2WI, DWI, T2WI+DWI, and T2WI+DWI+DCE. Calculate the sensitivity, specificity, and accuracy of T2WI, DWI, DCE, and PI-RADSv2 based MRI diagnostic peripheral zones, and plot ROC plots. Results A total of 23 cases of PCa were divided into 138 areas, with 67 areas of PCa, 71 areas of non-PCa, the t values of the PCa area were (4.29±0.85), (4.34±0.79), (4.49±0.61), (4.59±0.55) respectively, and the t values of non-PCa area were (2.69±0.89), (2.89±1.10), (2.97±0.95), (2.59±0.78) respectively. There was a significant difference in the PCa and non-PCa scores between the two groups (P<0.05). The sensitivity, accuracy, and AUC of PIRADS v2-based peripherial PCa diagnosis were higher than those of T2WI, DWI, and DCE. Conclusion Mp-MRI diagnosis based on PI-RADS V2 has high diagnostic value for peripheral PCa.
